Transfer UV maps not working properly
Transfer the Object Data from the Active object to the Selected object before you transfer the UV maps.

Object Mode: Object > Make Links > Object Data

Object Mode: Object > Make Links > Transfer UV Maps

This will retain any vertex groups on the original object if rigging has been set up etc.

This is useful for creating symmetric UV maps.

Duplicate object, delete half of new object, add Mirror modifier, Tick the 'U' under textures in mirror modifier, create UV, apply mirror, transfer object data, transfer UV maps.


Object Data: An entity in the scene with location, scale, rotation. Used by scenes &amp; groups.
